This week on the Science for Sport Podcast, host Richard Graves sits down with Nathan Spencer, Strength & Power Coach at the St. George Illawarra Dragons and former NBA Performance Coach with the Orlando Magic.

With over 15 years in high-performance sport, Nathan shares his unique journey from the pathways of Australian rugby league to the courts of the NBA, and now back to the NRL. The conversation dives deep into velocity-based training (VBT), practical insights into using data in elite environments, and the importance of education and context when applying technology in sport.

Whether you’re a coach, sports scientist, or performance professional, this episode is packed with actionable takeaways and thought-provoking discussions about how to truly leverage tech and data to improve athlete performance.
